Labelbox — Documentation & Integration Guide

API & Connectivity

Labelbox exposes a full API, enabling developers to programmatically trigger agents, configure workflows, manage sessions, and retrieve graded performance data. Agents can also be invoked via external events — including scheduled jobs, incoming alerts, repository commits, and direct API calls — making it straightforward to embed Labelbox into existing CI/CD pipelines and MLOps infrastructure.

Model Provider Configuration

Labelbox supports multiple AI model backends. Teams can configure agents to run on Claude, GPT, Gemini, or open-weights models, allowing flexibility to match model choice to task requirements, cost targets, or compliance constraints.

Integration Ecosystem

Labelbox connects natively with 24+ tools across key categories:

CategoryIntegrations
Dev & EngineeringGitHub, Jenkins, Vercel, Sentry
Data & MLBigQuery, Databricks, Snowflake, Looker, Google Cloud, Google Cloud Logging
CollaborationSlack, Jira, Linear, Confluence, Notion, Google Drive, Google Calendar

Agent Memory & Grading

Each agent session is graded, and results feed into a persistent memory layer that accumulates skills over time. This architecture supports continuous improvement loops without requiring manual retraining cycles.
